  • Publication number: 20210323651
    Abstract: The invention relates to a sandwich composite component (1) for the interior of a passenger aircraft. One problem to be solved by the invention is that of proposing a cost-effectively produced sandwich composite component which is suitable for the interior of a passenger aircraft and fulfils current fire protection requirements. The layer structure of the sandwich composite component (1) according to the invention comprises: a core layer (10) made of polymer foam; a reinforcing layer (20) comprising fiber composite material; and in addition at least one functional layer (50); wherein said layers of the layer structure are integrally bonded to each other, in particular by an adhesive bond. The fiber composite material of the reinforcing layer (20) comprises a woven or laid fabric made of reinforcing fibers and a polymer matrix, which has a higher density than the polymer foam of the core layer (10).

  • Publication number: 20210299992
    Abstract: A honeycomb for curved surface lightweight components includes a plurality of elongate ribbons and connecting regions. The connecting regions are provided, respectively, between opposing ribbons to connect the ribbons together in a portion-wise manner in a firmly bonded relationship in a transverse direction. The connecting regions are arranged at regular spacings along the longitudinal direction of a ribbon. Honeycomb-like cells form cavities between the ribbons. With respect to three successive ribbons, a displacement of the connecting regions between first and second ribbons relative to the connecting regions between second and third ribbons toward a first side of the longitudinal direction is lesser than toward a second side of the longitudinal direction.

  • Publication number: 20210291479
    Abstract: A honeycomb body made of a composite material for fire-resistant lightweight structures including honeycomb cells having a cross section is provided. The cell walls of the honeycomb cells are produced from a composite material. The composite material has at least one carrier, for example a woven fabric or a laid fabric made of fibers, and a matrix into which the carrier is embedded. The matrix includes a silicon-based ceramic material, of which the proportion by mass in the matrix along the cell walls is at least 30 wt. %. A method for producing such a ceramic honeycomb body and a honeycomb tube as an intermediate product for the same are also provided. A flat semi-finished product as a curable intermediate product for the production of fire-resistant fiber composite lightweight structures, which has a matrix mixture including dispersed silicon particles, is also provided.

  • Patent number: 9909844
    Abstract: Armor plating is provided for armored land vehicles or watercraft, the armor having a base armor plate and an additional armor plate fixed thereto on the enemy side, such that it can be removed. A structural component can be used as a base armor plate for such vehicles, and comprises a layered structure with a core composite having an inner honeycomb core and at least one covering layer. The layered structure does not contain supporting metal layers or ceramic, hard material layers. Another essential characteristic is the use of fixture elements which are anchored in the core composite to allow additional armor plating to be detachably fixed on the enemy side. The core composite therefore essentially offers basic protection itself, while also acting as the carrier structure for interchangeable additional armor plating.

  • Patent number: 9233570
    Abstract: A multi-layer, expandable sleeve (100) for a printing press cylinder and a method of manufacturing this expandable sleeve are provided. The sleeve has an inner layer (110) with a hard surface inner jacket (112), which defines a longitudinal axis (A) and the cavity for mounting on the cylinder, and an outer layer (130) with a cylindrical outer jacket (132) for carrying an outer shell, a printing plate or a separate outer sleeve, in particular. An intermediate layer (120), manufactured in the form of a lightweight honeycomb having honeycomb cells oriented radially (B) to the longitudinal axis (A), is provided between the inner jacket (112) and the outer jacket (132). The intermediate layer (120) includes at least one honeycomb layer (122-1, 122-2, 122-3, 122-4, 122-5) of fiber composite honeycomb consisting of fiber material embedded in a resin matrix that has been applied coaxially around the longitudinal axis (A).
